bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

q = Conditional

bit 7

SOSCR: Secondary Oscillator Ready bit

If T1OSCEN = 1:

1 = Secondary oscillator is ready

0 = Secondary oscillator is not ready

If T1OSCEN = 0:

1 = Timer1 clock source is always ready

bit 6

Unimplemented: Read as ‘0’

bit 5

OSTS: Oscillator Start-up Timer Status bit

When the FOSC<2:0> bits select HS, XT or LP oscillator:

1 = OST has counted 1024 clocks, device is clocked by the FOSC<2:0> bit selection

0 = OST is counting, device is clocked from the internal oscillator (INTOSC) selected by the IRCF<3:0>

bits.

For all other FOSC<2:0> bit selections:

See Table 5-2, “OSTS Bit Definition”.

bit 4

HFIOFR: High-Frequency Internal Oscillator Ready bit

1 = HFINTOSC is ready

0 = HFINTOSC is not ready

bit 3-2

Unimplemented: Read as ‘0’

bit 1

LFIOFR: Low-Frequency Internal Oscillator Ready bit

1 = LFINTOSC is ready

0 = LFINTOSC is not ready

bit 0

HFIOFS: High-Frequency Internal Oscillator Stable bit

1 = HFINTOSC 16 MHz Oscillator is stable and is driving the INTOSC

0 = HFINTOSC 16 MHz is not stable, the Start-up Oscillator is driving INTOSC
